Greater Yellowstone

There are so few large, nearly intact networks of wildlands left on earth. Greater Yellowstone is one of the last.

Greater Yellowstone is defined by blue-ribbon trout streams, grizzly bears and the longest wildlife migration corridor in the continental United States. But these treasures are now threatened by expanding energy development pressures and growing populations.

At Wilderness, we're working to protect this iconic American wildland from these threats and preserve the landscape's natural and human benefits.

Stories from Greater Yellowstone

  • For this report, The Wilderness Society reviewed data from more than 16,000 parcels auctioned off by the state. The analysis details more than a century of land sales that have privatized and closed off an amount of once-accessible lands nearly the size of the entire Sawtooth National Forest. Parcels often end up in the hands of some of Idaho’s biggest industries, while others have been turned into gravel pits, strip malls and even exclusive private fishing retreats and lakeshore hideaways for those wealthy enough to buy them.
